# Insert two geometric means between 9 and 243.

Answer :

To find: Two geometric Mean

Given: The numbers are 9 and 243

Formula used: (i) r , where n is the number of

geometric mean

Let G_{1} and G_{2} be the three geometric mean

Then r

⇒ r

⇒ r

⇒ r

⇒ r = 3

G_{1} = ar = 9×3 = 27

G_{2} = ar^{2}= 9×3^{2} = 9×9 = 81

Two geometric mean between 9 and 243 are 27 and 81.
